Babelscape is a high-tech Sapienza startup company founded in 2016 focused on multilingual Natural Language Processing with the main goal of enabling multilinguality and text understanding in customers’ applications which deal with text in different ways. Thanks to technological transfer from the internationally renowned Natural Language Processing research group headed by prof. Roberto Navigli at the Sapienza University of Rome, winner of two European Research Council grants and of several international awards, the company places itself on the market with very high professional profiles and the ability to tailor its solutions to the customers' needs.
The company's core mission is to overcome the language barriers by enabling the automatic processing of text independently of the input language, and distilling and aggregating the information extracted across languages by means of a unified large-scale multilingual knowledge repository and semantically-enhanced text comprehension systems.
About Sapienza NLP
The Sapienza NLP Group in the Department of Computer Science at the Sapienza University of Rome is a research team led by prof. Roberto Navigli which currently includes around 20 members, among Ph.D. students and Postdocs. The group focuses on multilingual Natural Language Understanding, including multilingual lexical and sentence-level semantics, multilingual resource creation (BabelNet, VerbAtlas, SensEmBERT, Train-O-Matic, and many others), with state-of-the-art systems for multilingual and cross-lingual Word Sense Disambiguation, Semantic Role Labeling, Semantic Parsing. 
The group is currently funded by two EU projects, an ERC Consolidator Grant (MOUSSE) and the ELEXIS European electronic lexicographic infrastructure, and an Italian project (PerLIR), with several ongoing international collaborations.
